My invention relates to portable drill.

The object of my invention is to provide a simple and eflicient and easily operable portable machining device in which various tools can be used; by means of which various tools can be rotated; which can reach into otherwise inaccessible places to perform a ymachining operation therein; in which the moving mechanism is inclosed in a casing; which has means to receive and hold a quantity of lubrication material to insure continued lubrication of the moving members in the device. Y

Other objects will be pointed out below in this specification or will become obvious or apparent or will suggest themselves upon an inspection of this specification and the accompanying drawing.

I attain my object by the mechanism shown in the accompanying drawing in Which:

Fig. 1 is a side view of a portable machining device, a drilling device, embodying my invention, partly in section to show interior relations and having an angular relation bef tween the driving spindle and the driven or drill rotating spindle thereof.

Fig. 2 is a perspective view, on a larger scale, of the inner ends o-f the driving and ,e driven spindles of Fig. l. Y

Fig. 3 is a perspective view, on a larger scale, of the link member of the connector means for connection of the spindles.

Fig. i is a perspective view, on a larger scale, of the stub members of the connector means for connection of the spindles.

Fig. 5 is a transverse section, on a larger scale, taken in a plane indicated by the line 5 5 in Fig. 1.

Similar reference characters refer to similar parts throughout the views.

Quite frequently it is desirable or necessary or convenient to drill a hole or perform another machining operation or a driving operation for a screw and the like in or ona. wall which is not open for direct access thereto with the usual tools or devices or where for other reasons the working space between that wall is limited so that the usual tools can not be used or where the wall is otherwise inaccessible or inconveniently accessible.

K screw 19.

Since the usual tools can lnotfbe'used directly,

vit* is necessary that; suiiicientroom" or p space must be madeby` removal of4 obstructions which must'be replaced after ythemachining u or other operation'is completed, or'a'special 35 tool or device must be made, :aill'of which requires time and expense." "1 i l y invention provides a'ldevicejwhichrcn reach into narrow spaces, as between two walls, and'perform' an operationen either one or on both of the walls or on any other element in the space and thereby saves vcoun*- siderable time and expense. l
